Spent some time shooting the new Xtreme 12.5" barrel this weekend. I gotta say, I wasn't thrilled - at first. Every other round FTL or FTE, no FTF though. Took me a while to figure out why. The Butler Creek loader I used was denting the casings (piece of crap), therefore cocking the bullet head and f'ing it up. I loaded a mag by hand, every single round loaded and fired perfectly. Guess the bulk Blazer is just fine with the Bentz chamber.
Thought you Nutz would like to know!
